These are all sounds from an electric six string contrabass tuned in fourths from the low A on the piano up, with strings A D G C F Bb recorded using Cool Edit Pro. The lowest string plays the first eight notes, then there are five on each subsequent string until we get to the Bb string, which plays all the rest. I will probably do a set with vibrato and a growlier tone, and maybe a set using all notes on all strings. There is a picture of the bass used in the pack athttp://infohost.nmt.edu/~jstarret/contrabass.html
